ELECTRIC HEATER FOR VAPOR FUEL.

Specification of Letters Patent.

Patented Apr.18, 1922.

To all whom it may concem:

Be it known that I. BENNARD H. Pounnor, a citizen of the ll'ii'ited States ,;.;resid in at Rochester, in the countyof Monroe and tate of New York, have-;.invented certainnew and useful Improvements in Electric Heaters for o f' which the following is a.

at the end thereof."

In tliedrawings,

Fig-'13s a view partly in section of the intake or manifold of an automobile engine,

showing the electric heater in place.

,Fig. 2 is a vertical section on the line 2 "2 of Fig. 1, looking at it from above.

Fig. 3 is a plan View of the copper segmental plate. In the drawings, like reference numerals indicate like parts.

In the drawings, reference numeral 1 in-' dictates the intake pipe leading from the carburetor, and 2 indicates the tube leadingto the manifold. The pipe 1 is provide with the flange 3 and the tube 2 is provided with the flange 4, connected by the bolts 5 and 6, with the gasket 7 interposed between them. My improved heater consists of the oval or diamond shaped plates 8 and 9, made preferably of fiber or asbestos or any other suitable insulating material. These plates have a round opening through the middle, through which passes the mixture from the carburetor to the engine. Between these plates is fastened the copper segmental plate 10, having a bridge 11 spanning the opening, on which bridge is carried a stem orstandard 12. On this bridge is fastened a coil of resistance wire 13, the base ofwhich rests on an insulating strip of mica 15 or other suitable material to insulate it from the bridge which supports it. Over the lower coil is also placed a strip of mica 14 or other suitable insulating material to hold it in place.

At the top of the standard 12 is placed a copper washer 16, by which the resistance wire is held in. place. The standard 12 is made of brass and makes electrical contact with the wires at the top and with the bridge at the bottom, and the wire coil 13 does not make electrical contact with the bridge at the bottom. Fastened' to the free end of the wire coil at the bottom is the terminal 17 which is placed in the opening between the ends of the segment, which terminal is fastened to one pole of the battery in the car and to the other end of the wire is fastened the contact 18, which is connected to the other pole of the battery of the car. The contact 18 makes contact with the wire through the copper segment 10, the bridge 11 and the standard 12. Ordinarily the contact 18 will be grounded on the pipe and the contact 17 will be insulated from the pipe, so that connections can be easily made to both terminals. V

In practice,especially in cold weather, it is sufficient to close the switch 19 about one minute before the car is started and the current then heats the wire coil, which in turn heats the air or mixture on the inside of the manifold where the heat is most needed and where it can be the most efiectively applied. When the engine is turned over,- the heated air and mixture is drawn into the engine and usually starts the engine on the revolution.

I claim:

1. A heating apparatus, comprising a gasket between two flanged joints of pipe, said gasket having an opening therethrough in line with the opening in the pipe, a segmental conductor plate in said gasket, sald plate having a bridge therein spanning the opening in said ipe, a stem supported on said bridge, a coi of wire connected to said stem at the top andy'extending down to and insulated from the bridge, electrical connections connected to the ends of said coil, one of said connections being insulated from the pipe, whereby said coil in the pipe may be heated electrically from a source of power outside of the pipe.

2. A heating apparatus, compnsing gasket between two flanged joints of pipe, said gasket having an opening therethrough in line with the opening in the pipe, a segmental conductor plate attached to said of said connectionsbeing insulated from the pipe, whereby said coil in the pipe may be heated electrically from a source of power 10 outside of the pipe.

In testimony whereof I affix my signature.

BENNARD H. POMEROY.
